Construction Deficiency Report - Breakdown in Quality Assurance Program for Reinforcing Steel (50-458/79-01).
(Control of Non-Safety-Related Reinforcing Steel.) The inspector examined the progress of the constructor in marking and controlling non-Category I rebar.
The rebar was being marked with paint according to the prescribed proce-dures. FQC personnel were observed monitoring the activity. A controlled area (gate and lock) has been established.
Due to the long term nature of this item it is not considered resolved at this time.
3.
Site Tour The IE inspector conducted a tour of the River Bend site to observe con-struction activities.
